Patented Dec. 24, 1940 UNITED STATES MEANS FOR CONNE MAIN CTING BRANCHAND PIPE S Jean Le Gorre, Philadelphia, Pa.

Application October 6,

2 Claims.

The present invention relates to improvements in means for connecting abranch pipe to a main pipe in domestic Water and other supply systems;and, more particularly, to a form of litting including the usualT-iitting and the stop valve and Waste outlet.

The principal object of the `present invention is to simplify andcheapen the construction and to reduce the costs of application of themeans employed for connecting a main and a branch pipe While retainingthe stop Valve and waste outlet.

Other objects of the invention will appear from the followingdescription at the end of which the invention will be claimed.

Generally stated, the invention comprises a unitary or one-piece T-pipetting having an internal partition dening a through fluidway and abranch uidway and provided with a port, a valve co-operating with theport, and a Waste connection or outlet on the branch pipe side of thepartition.

The invention also comprises the improvements to be presently describedand finally claimed.

In the following description, reference will be made to the accompanyingdrawing forming part hereof and in which:

Fig. 1 is a View, partly in section, of a tting embodying features ofthe invention.

Fig. 2 is a sectional view taken at right angles to Fig. l, with thevalve and its stem and bonnet omitted.

Figs. 3 and 4 are, respectively, similar views illustrating amodification of the invention, and

Fig. 5 is a transverse sectional View illustrating another modification.

Referring to the drawing, and more particularly to Figs. 1 and 2, Igenerally indicates a T- iitting which, lof course, is hollow andconsists, in effect, of one-piece, such as a casting, or at any rate isa unitary structure. This fitting is provided With four outlets 2, 3, 4and 5, in respect to the interior of the fitting, although in part, theyoperate as inlets in respect to the ow of fluid through the tting. 6indicates an internal partition dening a through fluidway l' between theoutlets 2 and 3 and a branch fluidway 8 to the outlet 4. This partitionis provided with `a port 9 and with a valve seat l0. I l is a stop valveco-operating with seat I0, and its stem extends through the bonnet l2and is provided with a hand-piece not shown because it is too wellunderstood to require illustration.

In use, the described fitting is interposed in a 55 main pipe which isconnected with it at 2 and 3.

The branch pipe is connected with it at 4, and the Waste pipe isconnected with it at 5. The

1938, Serial No. 233,629

valve ll -operates as a stop valve for the branch pipe and, whether thevalve be opened or closed, the through fluidway for the main pipe isopen. It may be remarked that the tting is extremely simple inconstruction and it will be evident to 5 those skilled in the art thatit can be inexpensively applied or installed for the reason that thebranch pipe can be connected directly to the outlet 4; Whereas, inpresent installations with which I am familiar, the branch pipe outletis connected 10 t-o one end of a nipple and the stop valve is connectedto the other end of the nipple and the stop valve is connected to thebranch pipe, making three connections in all between the T-tting and thebranch pipe; Whereas, in the construction of 15 this invention, there isbut one connection between the branch pipe and the T-fitting whichembodies as a part of it the stop valve and the drain outlet.

The construction and mode of operation of the 20 modification shown inFigs. 3 and 4 are as above described except that the valve Il is notlocated in the through waterway as in Figs. l and 2 but is located onthe branch side of the partition 6.

The construction and mode of operation of the 25 modificationillustrated in Fig. 5 are as above described except that the partition 6is disposed at right angles to the through waterway, instead of parallelwith it. Thus there is provided a slight enlargement 'IEL of the throughiluidway.

It will be obvious to those skilled in the art to which the inventionrelates that modifications may be made in details of construction andarrangement and in matters of mere form without departing from thespirit of the invention which 35 is not limited in respect to suchmatters or other- Wise than as the prior art and the appended claims mayrequire.

I claim:

1. For connecting the end of a branch pipe to 4a the adjacent spacedends of a main pipe, a T- -tting having a single Wall and four openingsof which three receive the pipe ends and having a single internalpartition defining with the single Wall a constantly open straightthrough iluidway 45 and a branch uidway and provided with a port, saidiluidways lying in substantially a single plane, avalve co-operatingwith the port to control the branch fluidway only and having its stemperpendicular to said plane, and an independent 50 waste connection atthe fourth opening and on the branch pipe side of the partition.

2. Means for connecting a branch pipe to a main pipe substantially asdescribed in claim 1 and in which the T-tting including the throughiluidway is a unitary or one-piece structure.
